NAME

adv -- Advansys ISA/VL/EISA/PCI 8bit SCSI Host adapter driver

SYNOPSIS

To compile this driver into the kernel, place the following lines in your
kernel configuration file:
devicescbusdeviceadv
For one or more EISA cards:
deviceeisa
For one or more VL/ISA cards:
deviceisa
In /boot/device.hints:
hint.adv.0.at="isa"
For one or more PCI cards:
devicepci

DESCRIPTION

This driver provides access to the 8bit SCSI bus connected to the
Advanced Systems Products, Inc. ASC900, ASC1000, ASC1090, ASC1200,
ASC3030, ASC3050, and ASC3150 host adapter chips. The following tables
list the AdvanSys products using these chips, their bus attachment type,
maximum sync rate, and the maximum number of commands that can be handled
by the adapter concurrently.

Footnotes:
1. This board has been shipped by HP with the 4020i CD-R drive.
The board has no BIOS so it cannot control a boot device, but
it can control any secondary SCSI device.
2. This board has been sold by Iomega as a Jaz Jet PCI adapter.
3. This board has been sold by SIIG as the i540 SpeedMaster.
4. This board has been sold by SIIG as the i542 SpeedMaster.
5. This board has been sold by SIIG as the Fast SCSI Pro PCI.

Per target configuration performed in the AdvanceWare menu, which is
accessible at boot, is honored by this driver. This includes
synchronous/asynchronous transfers, maximum synchronous negotiation rate,
disconnection, tagged queueing, and the host adapter's SCSI ID. The
global setting for the maximum number of tagged transactions allowed per
target is not honored as the CAM SCSI system will automatically determine
the maximum number of tags a device can receive as well as guarantee fair
resource allocation among devices.
